To install Bun:

curl -fsSL https://bun.sh/install | bash

npm install -g bun

brew tap oven-sh/bun

brew install bun

docker pull oven/bun

docker run --rm --init --ulimit memlock=-1:-1 oven/bun

To upgrade Bun:

bun upgrade

Bun.semver is a fast builtin SemVer parser

bun install's fast node-semver compatible parser is now available as a builtin Bun API: Bun.semver.

import { semver } from "bun";

semver.satisfies("1.0.0", "^1.0.0"); // true
semver.satisfies("1.0.0", "^2.0.0"); // false

const versions = ["2.1.0", "1.0.0", "1.0.1", "1.1.0", "2.0.0", "2.0.1"];
versions.sort(semver.compare); // ["1.0.0", "1.0.1", "1.1.0", "2.0.0", "2.0.1", "2.1.0"]

It's 20x faster than node-semver, and passes node-semver's test suite.

Fixed: Semver sorting bug with build tags

Previously, Bun was sorting semver versions incorrectly when build tags with multiple segments containing the . character were present. This has been fixed, thanks to @dylan-conway.

Fixed: = and v prefix in package.json versions

Previously, Bun only supported = and v prefixes in dependency versions, but not in package.json versions. This has been fixed, thanks to @dylan-conway.

Fixed: potential crash when printing exceptions

A crash that has been present since before Bun v0.1.0 has been fixed. When displaying the preview of the source code that caused an exception, sometimes Bun would crash. This has been fixed.

Fixed: TLS handshaking error-handling issue

A bug in Bun.serve that could cause Bun to eventually no longer respond to incoming requests with client-side certificates has been fixed, thanks to @cirospaciari.

A bug impacting @google-cloud/storage has been fixed

A Node.js compatibilty bug caused @google-cloud/storage to not work as expected.

With DEBUG="*", it would print a message like this:

  retry-request Current retry attempt: 1 +0ms
  retry-request Next retry delay: 2351 +221ms
  retry-request Current retry attempt: 2 +2s
  retry-request Next retry delay: 4143 +150ms
  retry-request Current retry attempt: 3 +4s
  retry-request Next retry delay: 8135 +185ms
  retry-request Current retry attempt: 4 +8s
TypeError: undefined is not an object

This has been fixed. It no longer errors, and it no longer erroneously retries (which would cause it to take a long time to fail).

A bug impacting Astro has been fixed

A Node.js compatibility bug caused astro dev to return "file not found" errors when using Bun in v1.0.10. This has been fixed. We will soon add an integration test that runs Astro to prevent this from happening again.
